WALK-PAPER MACHINE.

Application filed April 5.

My invention consists of an improvement in means for placing wall paperonthe ceiling of room or other similar chamber. It has in view toprovide a light, portable, adjustable frame, capable of longitudinal adjustment for adaptation to varying heights and provided with means forsupporting the paper strip, means for accurately locating the strip, forapplying it to the ceilingsurface, for pressing it thereagainst, and forotherwise elfectually, economically and rapidly carrying out repeatedapplications of successive strips by means of the construction and usethereof, ashereinafter more fully described.

Ordinarily, in applying wall paper to ceilings, the usual practice is toutilizea supporting platform orboard for pasting, with hand placementand manipulation of the pasted strip, in connection with a step-ladderor other elevatedisupporting mechanism, requiring considerable skill andtime in applying the strips successively ovcr the surface.

In my invention I utilize a portable framework comprising, three mainfeatures or elements, to wit, (1) an extension clamping pole or. supportfor location between the floor and the ceiling, (-2) a detachableandadjustable paper strip support or platform, and (3.)v a detachableoperating or applying frame.

These several elements are so constructed and arranged to providev forerection, adjustment and operation, and for separation, collapsing, andclose assemblage for packing and transportation. The several parts arepreferably made of wood and light metal portions, contributing tolightness, strength and adaptability to use and manipulation, as hereinillustrated and described.

Referring to the drawings:

Fig. 7' is an enlarged cross section on the line VIIV II of Fig. 5;

Fig. 8 is-a vertical sectional view on the line VIII-VIII of Fig. 5,corresponding to the upper. portion of Fig. 3.

Referring to Figs. 1 and 2, the entire mechanism is shown in its initialtemporarilyw held position between the floor and the ceiling, forinitial application oftheend of the wall paper strip.

The main supporting framework consists of a pair of struts or poles2and3 respectively, arranged side by. side for sliding adjustment andfixedly held together in erected or collapsed, or any interveningposition by means of transverse bolts. 4 extending through slots 5] andhaving tightening and loosening, thumb nuts 6 with U-shaped sheet metalguiding washers 7. By such means the struts 2 and 3 may be adjusted withrelation. to each other, for extension as in Figs. 1 and 2, orlongitudinal collapse, for portability and packing.

Strut 2 is provided at its lower end with a floor engaging shoe member 8which, may conveniently be made of sheet or plate metal concaved at itsmiddle portion as at 9, providing terminal points for anchoringengagement against the floor surface. A pedal or stirrup 10 is fixedlysecured to strut 2 immediately above shoej ti for holding engagement bythe footof the user.

Strut 2 and its companion strut 3 are provided with holding lugs orabutment-s 11,12, respectively, by which they may be manipulated inlengthening or shortening the main two-part standard.

.Strut 3 is provided at its upper portion with a two-part housingcomposed of oppositely located channel members 13, riveted thereto asat- 14, and projecting above the upper end"! of the strut 3, providing asocket extension for insertion and adjustable mounting therein of theupper operating frame. 1 i

Channel" members 13" are spaced sufliciently apart from each other toprovide between their flanges the intervening longitudinal slots 15 atopposite edges, through which extends the clamping bolt 16 provided withthe thumb nut 17, by which the standard of the adjustable operatingframe is variably mounted between the upper ends of channel members 13.

The adjustable operating frame, by which the strip of paper is guidedand applied to the ceiling surface, consists of a middle vertical postor stem member 18 to which are connected by upper and lower transverseframing members 19 and 20 the outer spaced apart vertical framingmembers 21. Said members as thus arranged provide a rectangularcomparatively flat support for the upper cross bar member 22, formingthe upper terminal main portion of the adjustable operating frame.

Bar 22 is provided at its opposite ends with upwardly extending terminalplate members 23, adapted to provide guiding clearance space for thestandard width of paper strip, of say eighteen inches in width. Plates23 are secured to the ends of bar 22 in any suitable way as by screws 24and are provided at their middle portion with inclined slots, 25, forreception of the narrow base 26 of the wiping brush 27. Such brush isremovably inserted in the slots in the manner shown in Fig. 3, forwiping engagement against the under side of the paper strip inapplication to the surface. The brush is at other times placed insuitable receiving clamps 28 secured by screws 29 against the rear faceof post members 21, as in Fig. 4.

Plates 23 are provided at their upper opposite corners with points 30,adapted to engage the ceiling as in Fig. 1, in initial placement of theframe, for temporarily holding it in position, when fully extended andheld by the tightening bolts 4.

At the rear side of the upper adjustable operating frame I provide ameasuring device consisting of a pair of strips 31 of fabric or othersuitable flexible material, secured at their upper ends to outwardlyextending brackets 32 on uprights 21, and having a terminal connectingcross bar 33 of thin wood or other suitable material.

Bar 33 is adapted to be extended as in Fig. 1 to the full length of thefabric strips 31 to any desired extent, as say one yard, for measurementand location of the frame outwardly beyond the adjacent wall. Otherwise,when not in use, strip 31 is folded around terminal bar 33 and placed ortucked into and behind a receiving and holding clamp 34 therefor,secured to and extending upwardly and outwardly from middle post member18, to which it is held by screws 35. The lower portion of such clampextends below such fastening connection and is turned upwardly,providing a hook 36, for support thereon of a smoothing brush 37, havingan interfitting hook 38 for such attachment, as in Fig. 8.

As shown in Figs. 3 and 5, the lower end of post 18, when in erectedposition for ceiling engagement by points 30, is spaced upwardly abovethe upper end of main post 3 any suitable distance, as say one inch,providing such intervening clearance, as at 39, Figs. 3 and 6.

The purpose of such clearance is to provide, to alimited degree, forlowering movement of the upper frame, after it has been clamped betweenthe floor and ceiling, for suflicient lowering of the upper frame uponloosening bolt 16, for retraction and clearance, providing for placementof the wiping brush on the top of the frame.

For such placement and easy running thereover I provide a roller 40pivotally mounted at 41 in brackets 42 extending outwardly from sidebars 21, shown.

For the purpose of temporarily supporting the reversely folded andpasted length or strip of wall paper, as previously pre pared by anysuitable means, as by the use of the machine shown in my prior application filed February 19, 1927, Serial No. 169,597, I provide a supportingplatform 43 which is detach-ably mounted and temporarily erectedoutwardly from the lower front portion of the upper adjustable frame, asin Fig. 3.

For such purpose platform consists of a comparatively light thin boardof paper or other suitable stiff material, braced by cross bars 44 and45, and provided at its inner corner portion; with holding brackets 46.These are formed of sheet or plate metal riveted to the inner cornerportions of the board and reinforcing blocks thereof, as indicated at47, and are provided at their inner portions with holding slots orsockets 48, 49, for engagement with laterally extending studs or screws50.

Pivotally connected, by hinge 51, to the front face of post 3 is a brace52 having interfitting connection with an interlocking lug 53, by aco-acting latch 54 at the upper end of the brace, as in Fig. Brace 52,when detached, lies downwardly alongside the front face of post 3, whileplatform or support 43 may then be bodily detached, when not in use.

From the foregoing description its construction will be'readilyunderstood.

In use, the paper supporting platform having been erected and themeasuring tapes 31 having been removed by withdrawing their terminal bar33 from its holding socket, the frame is spaced outwardly from the walla to the desired position corresponding to the length of the strips, andthen temporarily clamped by extension and tightening, as in Fig. 1.

The upper end of the already pasted strip of wall paper is drawnoutwardly over roller 40 to the corner terminal of ceiling b and theresecured, either by upward pressing of ltl bar 33 and rubbing of the sameacross underneath the paper, or by a separate brush as desired.

Bar 33 and strips 31 are then dropped, as indicated in Fig. 3;tightening bolt 16 is loosened and the upper fran'iework is lowered withits post 18 resting against the upper end of member 3 and leaving acorrespond ing space between points 30 and the ceiling surface. Byslight tipping forwardly, sufficient space is provided for the insertionin slots 25 of the wiping brush 27, which Will then press upwardlyagainst the under side of the paper strip, when the frame is returned tovertical position.

The operator then moves the entire framework across the room area, inthe same general direction as that defined by the already pasted portionof the strip, the remaining strip being thus drawn upwardly over roller40 and between brush 2? and the ceiling, and applied across theremaining ceiling area clear to the other end.

The application of the paper strip in this manner is renderedcomparatively easy, rapid and accurate. It may be drawn upwardly fromthe platform, unfolding in one direction and another from the originalcompacted layers, or by dropping of platform 43 it may hang downwardlvas in Fig. 2. \Vith either arrangement the direct and rapid applicationof the paper, with accompanying brushing action and pressure, is quicklyand accurately accomplished, without necessity of using any supplementalmechanism, platform, step-ladder, or other usual mechanism.
